In 1965, Congress added Title VI to the Elementary and Secondary Education Act of 1965. This created a Bureau of Education for the Handicapped however, educating students with disabilities was not yet mandated by federal or state law. The creation of the Bureau meant that change was coming.
In 1975, the Education for All Handicapped Children Act (EAHCA) was enacted. Prior to EAHCA, children with disabilities were often denied an education. Along with some supreme court decisions, EAHCA mandated all school districts to educate students with disabilities.
In 1990, the Americans with Disabilities Act (ADA) was enacted. With this enactment and the adoption of the Section 504 regulations, "504 Plans" become more common in school districts.
In 1990, the EAHCA was amended and became known as the Individuals with Disabilities Education Act (IDEA). This amendment required school districts to provide transition services for students with disabilities.
In 2001, the law No Child Left Behind was enacted. This law requires that all students, including students with disabilities, be proficient in math and reading.
In 2004, IDEA was reauthorized; calling for more accountability at the state and local levels. Additionally, school districts have to provide adequate instruction and intervention for students with disabilities and provide the least restrictive environment.
